NOlT-REFILLAB LE BOTTLE.

To all whom it may concern:

5e it known that I, MAURICE V. GnirriN, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in lloirltetillablellottles; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the ac companying drawings, and to the ligures of reference markedthereon, which term a part of this specification.

My invention relates to improvements in non-refillable bottles, myobject being to provide an article of this class which shall be ofsimple and economical construction, and which shall etl'ectually performthe function or a bottle of this character.

ln my improved construction a plug is inserted in the neck of the bottlecontaining a valve, the plug being so constructed that when the bottleis in the upright position, or in a position to allow liquid to Howthereinto, the valve will be seated to prevent the entrance of liquid;but when the bottle is tilted to allow the liquid to How therefrom, thevalve will be unseated and the liquid permitted to How tree y. Provisionis also made to prevent the introduction of an instrument tor thepurpose of holding the valve in the unseated position.

Having brietly outlined my improved construction, 1 will proceed todescribe the same in detail, reference being made to the accompanyingdrawing, in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a central, vertical section taken throughthe neck of a bottle equipped with my in'iprovement. Fig. 2 is a similarsectional view showing the bottle tilted to allow the liquid to flowtherefrom. Fig. 3 is a sectional view in detail of the non-refillablemechanism. Fig. 1 is a detail view of one member of the plug. Fig. is anunderneath View of the same.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the neck of a bottle which may be ofordinary construction except that it is provided with an interiorcircumferential groove 6 adapted to receive a spring ring 7 which alsoengages a similar groove 8 formed in the inner member 9 of a plug 10,wlnch is inserted in the Specification of Letters Patent.

neck of the bottle and held in place by the said ring. The member 2) otthe plug is chambered, as shown at 12. This chamber is trusto-conical inshape, and in it is located a ball valve 13 which, when the bottle is inthe upright position, is seated in the lower part of the chamber 12,thus preventing the entrance of liquid to the bottle. The plug 10 alsoincludes an outer member 11, which is applied to the member 2) in such amanner that the two parts form substantially an integral device. itsshown in the drawing, the member 14 is provided with an exteriorlylocated circumferential shoulder 15, which engages the upper extremityor the member 9. These two members are also provided with inclined faces16 and 1? respectively, which are in contact with each other, forming asurface of considerable area and making it practicable to cement the twoparts together as securely as may be desired. The member 14 is providedwith a central opening 18, communicating directly with a chamber 19whose outer portion extends upwardly, as shown at .20, and communicateswith a groove 21 formed in the member it above the chamber 19. From thegroove 21 a series of orifices 22 lead downwardly and communicate withthe chamber 12 of the member 9. It will thus be seen that an irregularpassage is formed from the central opening 8 of the chamber 12, makingit im possible to introduce an instrument into the last named chamberfor the purpose of holding the valve in the unscated position forfilling purposes.

The plug 10 can be made of any suitable material, as porcelain or glass.This is also true of the Valve 13.

Assuming that the plug is made in two parts, the valve 13 is placed inthe chamber 12 before connecting the members 9 and 1st of the plug.These members are then con nected in any suitable manner, as by asuitable cement, by tusion or otherwise, as may be found practicable ordesirable. The spring ring 7 is then placed in the circumferentialgroove 8 of the plug member 9 and pressed thereinto, to allow the plugto be inserted in the neck of the bottle. The plug is then moveddownwardly in the bottle neck until the spring ring reaches the interiorgroove (3. The ring then springs outwardly and occupies the two grooves(3 and 8 whereby the plug is locked within the bottle neck againstremoval. The plug is, of course, in-

serted in the neck of the bottle after the lat ter has been filled withwhatever liquid it is desired to place therein. It will then beunderstood that when the bottle is in the upright-position, or in anyposition that will allow the liquid to flow thereinto by gravity, theball valve will be seated and prevent the entrance of the liquid. Again,when the bottle is tilted sufliciently to allow the liquid to flowtherefrom, the ball valve will be un seated by gravity and allow theliquid to flow freely therefrom. The seated position of the valve isshown in Fig. 1, while its unseated position is shown in Fig. 2.

The desirability of a bottle of this character is well understood bybottlers of high class goods, since without a non-refillable attachment,it becomes practicable for the manufacturers of goods of inferiorquality, to refill bottles bearing the labels of the superior goods,thus enabling the manufacturer of the inferior article to palm olf hisgoods upon the public for those of superior quality. This not onlyinjures the manufacturer of the original contents of the bottle, butalso imposes upon the public. The object of my improved construction isto provide a bottle which will make such frauds impracticable.

Having thus described my invention, what I claim is:

1. A non-refillable bottle, comprising a bottle, a plug fixedly insertedtherein, the said plug containing a valve chamber, a ball valve insertedin said chamber, the latter being frusto-conical with its smallerextremity lowermost, whereby the valve is caused to seat when the bottleis in the filling position and to unseat when it is in the dischargeposition, the upper part of the plug having a central opening and asecond chamber interposed between said opening and the valve chamber,the plug having an irregular passage whereby the two chambers are placedin commui'lication with each other.

2. A non-refillable attachment for bottles, comprising a plug having aninterior valve chamber frusto conical in shape, the upper part of theplug having a central opening and a second chamber interposed betweenthe valve chamber and said opening, the plug having also an irregularpassage connecting the two chambers the second of which is in directcommunication with the central opening, and a ball valve located in thevalve chamber, the latter having its smaller extremity lowermost toallow the valve to seat when the bottle is in the filling position.

3. A non-refillable attachment for bottles, comprising a plug adapted tobe inserted in the neck of the bottle and provided with an interiorchamber, and a ball valve located therein, the said chamber beingfrusto-conical, the upper part of the plug having a central openingcommunicating with a chamber formed between the said opening and thevalve chamber, and an irregular passage forming a communication betweenthe two chambers, substantially as described.

In testimony whereof I ailiX my signature in presence of two witnesses.
